20 世纪 60 年代中期，以本地 Metrosideros polymorpha（’öhi’a lehua）为主的雨林的林分被观察到呈下降趋势（Mueller-Dombois 和 Krajina 1968）。在莫纳克亚山和莫纳罗亚山海拔 600 至 1700 米之间的迎风山坡上，许多树木正在死亡。对覆盖两个山坡的 80 000 公顷样本区进行的航拍照片分析显示，1954 年，该地区北部约 120 公顷出现了严重的枯萎病。 1965年，枯死面积增加到16000公顷，并以不同大小的斑块蔓延到南部地区（莫纳罗亚山坡）。在 1972 年的航拍照片中，严重顶枯病的累计面积已增加至 34 500 公顷（Petteys 等，1975）。
In the mid-1960s, stand segments of the nativeMetrosideros polymorpha-’öhi’a lehua)-dominated rain forest were observed to decline (Mueller-Dombois and Krajina 1968). Numerous trees were dying on the windward slopes of Mauna Kea and Mauna Loa at elevations between 600 and 1700 m. An aerial photo analysis of an 80 000 ha sample area covering both mountain slopes revealed that in 1954 approximately 120 ha showed severe dieback in the northern part of the area. In 1965 dieback had increased to 16000 ha and spread to the southern area (the Mauna Loa slope) in variously sized patches. On the 1972 aerial photo set, the cumulative area of severe dieback had increased to 34 500 ha (Petteys et al. 1975).
